TIRE ron VEHICLE-WHEELS.

To all whom 15 may concern.'

Be it known that I, TOD J. MELL, a citizen of the Unitedv States,residing at Youngstown, in the county of Mahoning and State of Ohio,have invented certain new and useful Improvements in Tires for Vehicle-IVlieels; and I do hereby declare the following to be a full, clear.,land exact description of the invention, snc'h as will enable othersskilled inthe art to which it appe/rtains to make and use the same.-

My present invention relates to tires for vehicle wheels, particularlyto cushion tires designed for use upon trucks and vehicles `intended forheavy 'hauling'.

It has for its-object the production of solid rubber orelastictire-bodies reinforced at the baseY by non-stretchable strands adaptedto prevent stretchingand creeping of the tire upon its wheel-rim, andto`effectnally retain it in operative posit-ion regardless of whethersaid rim is of the open or clencher type. v

As a further ,objectthis invention contemplates no-vel means for unitingthe strands aforesaid with the body of the tire, means for prevent-ingsaid strands from cutting through the tire when in service. and a novelplan of embedding said reinforcing strands or cable spirally within thetire base.

The invention Will be hereinafter particularly described and pointed outin the claims following. y

In the accompanying drawings which form part of this application andwhereon like letters indica-te corresponding parts in Figure lrepresents a transverse section through the invention and Withincontained reinforcing strand spirally wound. Fig. 2 is a fragmentaryend, partly nntwisted, of the wire and textile elements composing thereinforcing and securing strands. Fig. 3 is a fragmentary portion of thetire base relativelyenlarged and a transverse section of one reinforcingstrand. Fig. 4 is a plan view of the base Specification of LettersPatent.

Application led December 23, l910. Serial No. 598,979.

as of a .configuration sui-table for use with wheel rims of the clenchertype, and provided with the flexible canvas or fabric inner lining Q.lVithin the base of tire body 1 beginning at a given point .as at 3,Fig. 4, and passing circumferentially through the tire in spiralarrangement is a non-stretchable reinforcing` member Je preferablycomposed of interwoven strands of wire 5 and textile threads (i, asshown by Fig. 2 of the drawings. .It intervals the member Je bisected byanchor-bars T provided with terminal balls 8 and projecting uponopposite sides of said reinforcing member as shown. lVliile the saidcontinuous member 1J( is itself embedded as a core in av jacket 9 of arubber compound adapted during vulcanization of the tire to assume arelatively vhard finish as compared with the elastic plate l0 isomitted; or by Fig. wherein said plate. and also covering 9 for themember -t are omitted.

In the course of construction the-reinforcing member et bisected byanchor-bars 7 is incased in its covering S) and the whole wound spirallyuponthe annular flat base 10, as indicated by Fig. 1 of the drawings.The balance of the tire body l is then builtup, and the entire structurevulcanized as usual in the manufacture of tires. but it will be notedthat the composition of both jacket 9 and annulus l() issuch that thesemembers assume a relatively hard and stift' rm when cured. .\.s aconsequence the reinforcing member it less likely to cut through thebase of the tire body when subjected to hard usage. or when the tire isapplied to its wheell rim initially. )'Ioieovcr. it may be noted thatwhen constructed and arranged tlie rubber compound adjacent to thenon-stretchable member -it during vulcanization actually enters andunites securely with the textilestrands of said member mosteffectually,and, owing to this fact, as also the anchorage afforded bybars 7,slipping or creeping of the tire body upon said reinforcing strand ispractically impossible, particularly since the acket or covering 9 andbody effectually interlock the tire body l upon its wheel rim whenpressure is applied to the structure'transversely by the addition of thewheel flanges as usual in mounting tires. This operation nat-urallycompresses Jthe tire-base, formed in dovetailed relation with thestrands and relatively hard casing or jacketff) aforesaid, from side toside of the structure rendering it physically impossible to withdraw thetire l, or any portion thereof, from its dovetailed confines between theadjacent coils of the reinforcing member 4; and outer covering or acket9.

Having thus described my'invention,`\vhat I claim and desire to secureby Letters Patent, is:

l. An elastic tire for vehicle Wheels com. prising in combination anembeddedv nonstretchable Vreini'forcing member encircling the structure,and a'nchor bars bisecting said ,reinforcing member at intervals.

2. An elastic tire for vehicle Wheels comn prising in combination anembedded nonl` stretchable reinforcing member encircling the structurecontinuously, a jacket of relatively hard material inclosing saidreinforcing member, and anchor bars bisecting said reinforcing memberand its inclosing acket at intervals.

3. An elastic tire for vehicle wheels comprising in combination anon-stretehable reinforcing member spirally arranged, zr jacket ofrelatively hard rubber inclosing said reinforcingmember, anchor barsbisecting said reinforcing member and its inclosing` jacket atintervals, and an annulus of relatively hard rubber beneath theconvolutes of said reinforcing' member.

In testimony whereof I aiiix my signature,

in presence of two subscribing witnesses. 'I OD J. MELL.
